Effect of Guided Imagery on Sleep Quality, State Anxiety, and Comfort in Patients With Acute Coronary Syndrome

The goal of this randomized controlled trial is to determine whether guided imagery, when added to routine care, can reduce state anxiety and improve sleep quality and comfort in adults with acute coronary syndrome who are being treated in a cardiac intensive care unit. The main questions this study aims to answer are: Does guided imagery reduce state anxiety compared with routine care alone? Does guided imagery improve sleep quality compared with routine care alone? Does guided imagery improve comfort compared with routine care alone? A total of 64 participants will be randomly assigned to either a guided imagery group or a routine care group using block randomization. Participants in the guided imagery group will receive routine care and listen to a standardized guided imagery audio recording through headphones twice a day for two consecutive days. Each guided imagery session will last approximately 15 minutes. Participants in the routine care group will receive the standard treatment and nursing care provided in the cardiac intensive care unit without guided imagery. Researchers will assess participants' anxiety, sleep quality, and comfort and compare the changes between the two groups.
